Fossils can be found all around us, in the deserts, in the rocks, and even by and in the seas.
When Scientists discover a fossil they try to date the fossil to see if they can determine when this fossil possibly lived and died they can us a chart to help them accomplish this time consuming task which is called the Fossil Record which contains records with all the once living plants and animal fossils on it. This table is broken down from Eons, to Eras which are then broken into Periods. There are three main eras, which had their own unique plant and animal life, the Eras were: Paleozoic- No life in the beginning until towords the end of this era Mesozoic- This era contained Reptiles, Dinosaurs, and later contained birds and small mammals Cenozoic-This era contained Mammals, Mamoths, Sabertooth Tigers, and Sloths.
Some of the most useful fossils are trace fossils, which are evidence of life, some examples include footprints, tools, coprolite etc. Coprolite, which is very useful is preserved feces, which can help scientists determine what the specimin was eating in that particular time.
There are many types of fossils, many places to find them, and many ways to date them and determinde what they are, above was a very short overview of Fossils.
